A general solution to orthotropic material plane problems
正交異性冪強化材料的平面應力應變分析I. a mtil ( iaxial elastic - plastic hardening - sofling constitutive model of concrete is proposed iii order to offer a nonlinear material model of concrete for space restoring force analysis of reinforced concrete members taking into account the softening behavior of concrete. the concrete material model is incorporated the elastic - plastic hardening fracturing constitutive model of concrete with the plastic - fracturing theory of concrete, modified without defining two loading functiomis, and based on five parameter power function failure criterion proposed by guo zheng - hai etc from tsingliua ( jniversity, or three parameter unified strength theory proposed by yu mao - hong from x ian iiaotong university
1 、將砼彈塑性硬化斷裂本構模型與塑性斷裂理論結合起來,並加以改進,但無需定義兩個加載面,以清華大學過鎮海建議的五參數冪函數或以西安交通大學俞茂宏建議的,參數統一強度理論作為砼的強度破壞準則,建立了砼多軸彈塑性硬化松馳本構模型,能為鋼筋砼構件空間恢復力分析提供砼非線性材料模型,並能反映砼材料的軟化段。The consolidating wave speed of ten concrete specimens within four kinds of composition was inspected in 28 days, and we got the analogical law that the value of consolidating wave speed changes with the increasing concrete strength : the consolidating wave speed decreases when the concrete strength increases, and they varies according with exponential function. so, the feasibility of the consolidating wave speed method was validated, and this method has the advantages that it can be used to testing fresh concrete strength real - timely
在實驗室監測四種配比共十組混凝土(砂漿)試件28天齡期內的固結波速,初步得出了固結波速隨混凝土強度增長而變化的規律:固結波速隨混凝土強度增長而降低,二者呈冪函數規律變化,而且各組試件的固結波速隨混凝土(砂漿)強度的增長有非常相似的變化規律,由此可知固結波速法檢測混凝土強度是可行性的,其優點是可以實時監測混凝土強度的增長。
